Application filed May 9,

To aZZ whom it may concern.

Be it known tha'tI, J on: EvANs,.a citizen of the 'ilnitedl States, andresident of Salt Lake City, in the 1 county of Salt Lake Improved ;Pin,jof which the following is a' full, clear, and exact descriptionf V i Myinvention relatesto a sorting pin, and

aims to provide a device of this nature which may; be utilized toadvantage in numerous applications, but which is primarily in tended tobe used in connection with "a sorting machine of the nature illustratedin filed January 26, 1921. v ,7

, It has been found "in connection with identifiying pins employed inconjunction with a sorting machine of the type illustrated that arelatively great amount of time was lost incident to effecting a detachment of, the sorted materials from the pine with which they wereassociated, and in certain instances where anoperatorhadnot'completelyopenedthe pin parts, a pullupon the material wasliabletoresult in the same beingtorn. I J p y p Thus it is an objectoffthe present invention to provide a. sorting device or pin formaterials which maybe utilized to ad-f vantage in connection witha'isorting'" ma: chine of the, type indicated, and, by means of which anattachmen'tand detachment of articles from these pins may be efie'cte'din an extremely simple manner. 1

A'further object ofthe present invention resides in the provision of apin, the parts of. which are normally locked, so'that any materialassociated with these parts will not he accidentally detached; from thesame. "A still \furthero-bject of this invention is that of providingapin, the'parts of which are normally looked as aforestated, butin whichthese parts will be unlocked in a semi-automatic'manner upon the pinreach ing its final position. i

lVith theseand further objects in mind my present invention aims toprovide apin comprising a plurality of parts movable with respect toeach other, and a piercing element forming the pin proper, which isadapted to, extendr -through thef'material to be retained, together withmeans whereby the pin will'be caused to normally remain in a positionat; which itf'will retain "said material, said pin further comprising aand State of Utah, have invented a newa'nd my previous applicationSerial 140085- 1922. Serial No. 559,638.-

structure which will permit of a movement of said pin to a releasingposition. 7

Reference is had to the attached sheet 0E drawings as illustrating onepractical embodiment of my invention, and it willbe seen in thesedrawings that;

(Figure 1 is a side elevation of a part of a sorting machine of thenature specified, and showing a pin of my improved constructioninassociation therewith.

Figure 2 is an enlarged sectional view taken along the line 2 2 and inthe direction of the arrows indicated in Figure 1 showing the' pin partsin locked position. Figure 3 is a yiew similar to Figure 2 but showingthe pin parts in unlocked posi tion, and further indicating in dottedlines the position which the parts assume during the detachment of thematerial from the pin, and V a Figure 4- is a'view of a slightlymodified portion of the sorting machine shown in Figures 1, 2 and ,8. 3In the embodiment illustrated" I have shown a pin in association with asorting machine of the type indicated in my .pre-

vious application, and thus in the present case the reference numeral 5indicates a rod, which corresponds to the rod 22 of the sorting machineaforementioned, the reference numeral 6 indicating the base memher orring of'the machine, corresponding to the member 12 of the previousapplication. However it will be noted that contrary to the constructionpreviously indicated a key isassociated with the rod 5, and adjacent thelower end of the same, this key being in the nature 01": a sleeve 7 presenting a downwardly extending flange and a base 9, which latterco-operates with the member 6 and serves to retainthe sleeve in properposition.

Now with respect to the pin illustrated in detail in Figures 2 and 3 itwill be noted that the same preferably includes a housing 10 providing acutout portion 11, this housing slidably carrying a U shaped member 12,the base of which extends beyond the body of the housing and is adaptedto encircle the rod 5, and when adjacent the lower end of the same, thesleeve aforedescribed. i V

' The housing 10 may also carry a tab 13 presenting an identifying mark14 whereby the articles associated with the pin may be properly sorted.The U shaped mem her 12 also has the end of one of its arms bentinwardly as at 15, and incident to the provision of a stop ain 16associated with the housing a movement of the U shaped member beyond apredeterminedpoint with respect to the housing is prevented due to thefact that the inwardly turned end is will engage the stop pin 16. Thesecond arm of the U shaped member 12 terminates in a point 17 whichnormally bridges the cutout portion 11, and it will be obvious that uponan article such as a cloth 18 having part of its body introduced intothe cutout portion subsequent to which the U shaped member 12 isprojected to the position shown in Figure 2, that the cloth will befirmly secured to the pin.

Now with a view of providing means servin to normally retain the partsin this position it will be noted that a dog 19 is pivotally carried asat 20 by the housing 10, and this dog has one of its ends extending intoa cutout portion 21 forming a part of the housing 12 its opposite endbeing capable of being swung into the path of travel of the bent end 15of the U shaped member 12. The dog 19 is normally retained in thisposition by means of a suitable type of spring :22 which presses againstthe rear taee'ot the last mentioned end of the dog 19 to produce thisresult, and to lock the member 12 normally against movement with respectto the housing when the former is projected within the latter.

Thus assuming that the parts are in such a position that the bent end 15of the member 12 lies adj acentto the stop pin 16 it will be understoodthat the cloth 18 may be extended into the cutout portion 11 of thehousing 10, subsequent to which a movement of the member 12 inwardlywith respect to the housing 10 will cause the point 1'? to pierce thecloth 18, and will also cause the dog 19 to move to the posit-ion shownin Fig. 2 in which a retraction of the member 12 will be prevented thusclosing the pin. It is to be understood that the foregoing operation ofthe parts occurs when the pin is used in conjunction with sortingmachineof the type specified while the pin is at the upper end of therod. Upon this pin now being released and incident to the action ofgravity, the same will slide downwardly along the rod 5, and due to thefact that the flange 8 of the sleeve 7 also extends downwardly it willbe obvious that this portion will ride into the cut-out part 21 of thehousing 10 upon the latter reaching a position adjacent the lower end ofthe rod.

Now upon an operator desiring to effect a detachment of the cloth 18, hecan do so upon merely grasping the cloth and pulling the same sidewise,as has been shown in Fig ure 3. Upon this occurring the outer end of thedog i. e. that part of the same which extends into the cutout portion21, will be brought into engagement with the flange 8 of the key, andthe dog will consequently be swung to the position shown in Figure 3.Upon a pull upon the cloth being continued it will be obvious thatincident to the engagementof this material with the edge of the cutoutportion 11 of the housing 10' that the latter will be, pulled downwardlyto the position shown in dotted lines in Figure 3, thus in other words,retracting the point 17 and permitting the cloth to be pulled free ofthe point. This latteroperation of course is not resorted to until thekey has either been completely filled or all of the clothes belonging toone batch have been placed upon the same and it will be obvious that itwill not be necessary for an operatorto effect a release of each clothseparately, but he will be enabled to grasp all of the materials so asto effect a simultaneous retraction of all of the pin parts. Further itwill be subsequently found that all of: the pins are now open or inother words ready for a second sorting operation, and that also all ofthese pins are now upon the key. This latter member may thus be detachedfrom the rod 5 and' applied to a pin rack (not shown) where the pinswill be available for association with materials as the same arereceived, the key being subequently capable of I e-association with therod. 7

Thus all of the objects of this invention have been accomplished, and itwill be appreciated that numerous modifications might be resorted tosuch as for instance a rod, in lieu of employing an extraneous sleevemight comprise a body 23 as in Figure 4 formed with an integral flange21 serving the same purpose as the flange 8 shown in Figures 1, 2 and 3.
